PROBLEM TO BE SOLVED: To provide a polyester film which has excellent moldability, when heated and molded, and has excellent elasticity and excellent shape stability (thermal shrinkage characteristics, thickness unevenness), when used as a molded article under an ordinary temperature atmosphere, to provide a polyester film for molding especially suitable for molding use, and to provide a molding member using the same. SOLUTION: This polyester film comprising a copolyester produced from an aromatic dicarboxylic acid component and a glycol component comprising ethylene glycol and a branched aliphatic glycol and/or an alicyclic glycol is characterized in that the 100% stretching stress in the longitudinal direction and that in the width direction are each 180 to 1,000 MPa at 25°C and 1 to 100 MPa at 100°C. The polyester for the molding is characterized by using the polyester film as a molding member. The molding member is characterized by using the polyester for the molding. COPYRIGHT: (C)2004,JPO |
